Question about JBL Charge 5 WiFi

I already have some Google Nest speakers. However, they are all not suitable for my balcony, as I want to operate the devices too far away from the socket. My question is, how well does the JBL with Chromecast built in, integrate with my Google Home? Can I assign the device to a group? Unfortunately this doesn't work with the Sonos Roam and the Sonos App on Android doesn't really convince me either. Looking for an alternative for this summer
